The present application claims priority under 35 U.S.C. § 119(a) to Korean application number 10-2016-0113798, filed on Sep. 5, 2016, in the Korean Intellectual Property Office, which is incorporated herein by reference in its entirety.
Various embodiments may generally relate to a semiconductor technology, and, more particularly, to a semiconductor apparatus and a system including the same.
As the capacities and the degrees of integration of semiconductor apparatuses are increased, various types of stack semiconductor apparatuses are being developed. In a stack semiconductor apparatus, a plurality of chips may be electrically coupled through wires or through electrodes and may be packaged into a single package. A semiconductor apparatus may operate by being coupled with an external device through pads. In the case where the number of chips configuring a semiconductor apparatus is small, then a loading to be coupled with a pad is not considered large and communication between an external device and the semiconductor apparatus may be performed relatively smoothly. However, as the number of chips configuring a semiconductor apparatus increases and a loading to be coupled with a pad increases, a problem may be caused whereby precise communication may not be able to be performed.
In an embodiment, a semiconductor apparatus may be provided. The semiconductor apparatus may include a package substrate, and a plurality of semiconductor chips. Wherein the package substrate and the semiconductor chips may be configured based on a load value of the semiconductor apparatus.
Hereinafter, a semiconductor apparatus and a semiconductor system including the same will be described below with reference to the accompanying drawings through various examples of embodiments.
The first semiconductor chip 120 may include a first main pad 121, a first auxiliary pad 122, and a first buffer 123. The first main pad 121 may be coupled with the first substrate pad 112. The first main pad 121 may be wire-bonded with the first substrate pad 112. The first auxiliary pad 122 may be wire-bonded with the second substrate pad 113. In the present detailed description, “couple” may be used as a term that may include all electrical coupling relationships using bonding wires, through electrodes, through-silicon vias or the likes, and may be used as a term that includes not only a case where two components are coupled directly but also a case where two components are coupled indirectly through another component or other components. ‘Wire bonding’ may be used as a term that means a case where two components are coupled directly by using bonding wires. The first buffer 123 may be coupled between the first main pad 121 and the first auxiliary pad 122. The output signal of the first buffer 123 may be provided to the internal circuit of the first semiconductor chip 120.
The semiconductor apparatus 100 may further include a second semiconductor chip 130. The second semiconductor chip 130 may be stacked on the first semiconductor chip 120. The second semiconductor chip 130 may include a second auxiliary pad 132. The second auxiliary pad 132 may be coupled with the second substrate pad 113. The second auxiliary pad 132 may be wire-bonded with the second substrate pad 113.
The first package ball 111 may be coupled with the first main pad 121 of the first semiconductor chip 120 through the first substrate pad 112, and may not be coupled directly or may be indirectly coupled with the second substrate pad 113, the first auxiliary pad 122 and the second auxiliary pad 132. Therefore, the first package ball 111 and the first substrate pad 112 may expect only the loading of the first main pad 121 and the first buffer 123, and the external device coupled with the first package ball 111 may expect only a loading for the first semiconductor chip 120. If a signal is received through the first package ball 111, the first main pad 121 may receive the signal from the first substrate pad 112, and the first buffer 123 may buffer and output the signal. Since the output of the first buffer 123 is coupled with the first auxiliary pad 122 and the first auxiliary pad 122 is coupled with the second substrate pad 113 and the second auxiliary pad 132, the signal buffered by the first buffer 123 may be transmitted to both the first and second semiconductor chips 120 and 130. Conversely, a signal outputted from the internal circuit of any one of the first and second semiconductor chips 120 and 130 may be inputted to the first buffer 123 through the second substrate pad 113 and the first auxiliary pad 122. A signal outputted from the internal circuit of the first semiconductor chip 120 may be inputted to the first buffer 123 through the first auxiliary pad 122, and a signal outputted from the internal circuit of the second semiconductor chip 130 may be inputted to the first buffer 123 sequentially through the second auxiliary pad 132, the second substrate pad 113 and the first auxiliary pad 122. The first buffer 123 may buffer the signal, and output the buffered signal to the external device through the first substrate pad 112 and the first package ball 111. The signal received or outputted through the first package ball 111 may be a bidirectional transmission signal. For example, the bidirectional transmission signal may be data or a data strobe signal. The first buffer 123 may be a bidirectional signal transmission circuit.
The second semiconductor chip 130 may further include a second main pad 131 and a second buffer 133. The second semiconductor chip 130 may be manufactured and fabricated on substantially the same wafer as the first semiconductor chip 120, and may have substantially the same configuration as the first semiconductor chip 120. The second main pad 131 may be coupled with the second buffer 133. While the second main pad 131 may be coupled with the second auxiliary pad 132 through the second buffer 132, the second main pad 131 may not be coupled directly with the first substrate pad 112. The second main pad 131 may not be wire-bonded with the first substrate pad 112.
Referring to
The first semiconductor chip 120 may further include a third main pad 124, a third auxiliary pad 125, and a third buffer 126. The third main pad 124 may be wire-bonded with the third substrate pad 115. The third auxiliary pad 125 may be wire-bonded with the fourth substrate pad 116. The third buffer 126 may be coupled between the third main pad 124 and the third auxiliary pad 125. The third buffer 126 may provide a signal received through the third main pad 124, to the third auxiliary pad 125 and the fourth substrate pad 116.
The second semiconductor chip 130 may further include a fourth main pad 134, a fourth auxiliary pad 135, and a fourth buffer 136. The fourth auxiliary pad 135 may be wire-bonded with the fourth substrate pad 116. Therefore, the second semiconductor chip 130 may receive a signal received through the second package ball 114, through the third buffer 126 and the third auxiliary pad 125 of the first semiconductor chip 120 and the fourth substrate pad 116. The fourth buffer 136 may couple the fourth main pad 134 and the fourth auxiliary pad 135. The fourth main pad 134 may not be wire-bonded with the third substrate pad 115.
The semiconductor apparatus 100 may further include a plurality of semiconductor chips which are stacked on the package substrate 110 and the first and second semiconductor chips 120 and 130. The plurality of semiconductor chips may include the same configuration as the second semiconductor chip 130, and may have the same electrical coupling relationship as the electrical coupling relationship of the components of the second semiconductor chip 130. The semiconductor apparatus 100 in accordance with a present embodiment allows the external device to expect only the loadings of the main pads 121 and 124 and the buffers 123 and 126 of the first semiconductor chip 120 through the package balls 111 and 114 and not to expect loadings of the other semiconductor chips. Hence, even though the external device is coupled with a semiconductor apparatus in which a plurality of semiconductor chips are stacked, a loading may be reduced as if the external device is coupled with a semiconductor apparatus which includes one semiconductor chip.
A signal received from the external device may be buffered by the first buffer 123, and the buffered signal may be transmitted to the respective semiconductor chips through the second substrate pad 113 and the auxiliary pads 122 and 132. Conversely, a signal outputted from each semiconductor chip may be provided to the first buffer 123 through the auxiliary pads 122 and 132 and the second substrate pad 113, and may be outputted to the external device through the first buffer 123, the first substrate pad 112 and the first package ball 111.
The second semiconductor chip 230 may include a second main pad 231, a second auxiliary pad 232, a third buffer 233, and a fourth buffer 234. In order for implementation of a present embodiment, it is sufficient that the second semiconductor chip 230 includes the second auxiliary pad 232 and the fourth buffer 234. Since the first to fourth semiconductor chips 220, 230, 240 and 250 may be manufactured and fabricated through the same processes and have the same configuration, it is illustrated that the second semiconductor chip 230 includes together the configuration of the second main pad 231 and the third buffer 233. The second main pad 231 may not be coupled directly with the first substrate pad 212. That is to say, the second main pad 231 may not be wire-bonded with the first substrate pad 212. The second auxiliary pad 232 may be wire-bonded with the second substrate pad 213. The third buffer 233 may be coupled between the second main pad 231 and the second auxiliary pad 232. The fourth buffer 234 may be coupled with the second auxiliary pad 232 and the third buffer 233. The fourth buffer 234 may be coupled also with an internal circuit INT of the second semiconductor chip 230.
The third semiconductor chip 240 may include a third main pad 241, a third auxiliary pad 242, a fifth buffer 243, and a sixth buffer 244. In order for implementation of a present embodiment, it is sufficient that the third semiconductor chip 240 includes the third auxiliary pad 242 and the sixth buffer 244. Since the first to fourth semiconductor chips 220, 230, 240 and 250 may be manufactured and fabricated through the same processes and have the same configuration, it is illustrated that the third semiconductor chip 240 includes together the configuration of the third main pad 241 and the fifth buffer 243. The third main pad 241 may not be coupled directly with the first substrate pad 212. That is to say, the third main pad 241 may not be wire-bonded with the first substrate pad 212. The third auxiliary pad 242 may be wire-bonded with the second substrate pad 213. The fifth buffer 243 may be coupled between the third main pad 241 and the third auxiliary pad 242. The sixth buffer 244 may be coupled with the third auxiliary pad 242 and the fifth buffer 243. The sixth buffer 244 may be coupled also with an internal circuit INT of the third semiconductor chip 240.
The fourth semiconductor chip 250 may include a fourth main pad 251, a fourth auxiliary pad 252, a seventh buffer 253, and an eighth buffer 254. In order for implementation of a present embodiment, it is sufficient that the fourth semiconductor chip 250 includes the fourth auxiliary pad 252 and the eighth buffer 254. Since the first to fourth semiconductor chips 220, 230, 240 and 250 may be manufactured and fabricated through the same processes and have the same configuration, it is illustrated that the fourth semiconductor chip 250 includes together the configuration of the fourth main pad 251 and the seventh buffer 253. The fourth main pad 251 may not be coupled directly with the first substrate pad 212. That is to say, the fourth main pad 251 may not be wire-bonded with the first substrate pad 212. The fourth auxiliary pad 252 may be wire-bonded with the second substrate pad 213. The seventh buffer 253 may be coupled between the fourth main pad 251 and the fourth auxiliary pad 252. The eighth buffer 254 may be coupled with the fourth auxiliary pad 252 and the seventh buffer 253. The eighth buffer 254 may be coupled also with an internal circuit INT of the fourth semiconductor chip 250.
In the case where the package ball 211 receives and outputs a bidirectional transmission signal, the first to eighth buffers 223, 224, 233, 234, 243, 244, 253 and 254 may be bidirectional transmission circuits. For example, the first to eighth buffers 223, 224, 233, 234, 243, 244, 253 and 254 may include transmitters and receivers. In the case where the package ball 211 receives a unidirectional transmission signal, the first to eighth buffers 223, 224, 233, 234, 243, 244, 253 and 254 may be unidirectional transmission circuits. For example, the first to eighth buffers 223, 224, 233, 234, 243, 244, 253 and 254 may include only receivers.
Operations in the case where the semiconductor apparatus 200 receives and outputs a bidirectional transmission signal will be described below. The semiconductor apparatus 200 may receive a signal through the package ball 211 from the external device. The signal may be inputted to the first buffer 223 through the first substrate pad 212 and the first main pad 221, and the first buffer 223 may buffer the signal and output the buffered signal to the second buffer 224 and the first auxiliary pad 222. The second buffer 224 may buffer the signal outputted from the first buffer 223, and provide the buffered signal to the internal circuit INT of the first semiconductor chip 220. Further, the signal outputted from the first buffer 223 may be provided to the fourth buffer 234, the sixth buffer 244 and the eighth buffer 254 through the first auxiliary pad 222, the second substrate pad 213 and the second to fourth auxiliary pads 232, 242 and 252. The fourth buffer 234 may buffer the signal outputted from the first buffer 223 through the second substrate pad 213 and the second auxiliary pad 232, and provide the buffered signal to the internal circuit INT of the second semiconductor chip 230. The sixth buffer 244 may buffer the signal outputted from the first buffer 223 through the second substrate pad 213 and the third auxiliary pad 242, and provide the buffered signal to the internal circuit INT of the third semiconductor chip 240. The eighth buffer 254 may buffer the signal outputted from the first buffer 223 through the second substrate pad 213 and the fourth auxiliary pad 252, and provide the buffered signal to the internal circuit INT of the fourth semiconductor chip 250.
The first buffer 223 may buffer the signal received from the external device, and transmit the buffered signal to the first to fourth semiconductor chips 220, 230, 240 and 250. Accordingly, signal transmission and/or reception between the semiconductor apparatus 200 and the external device may be performed through the first substrate pad 212, the first main pad 221 and the first buffer 223, and signal transmission and/or reception in the semiconductor apparatus 200 may be performed through the second substrate pad 213 and the respective auxiliary pads 222, 232, 242 and 252. Since the semiconductor apparatus 200 is coupled directly with the external device only through the first main pad 221 and the first buffer 223, a loading which the external device expects for the semiconductor apparatus 200 may be retained as a constant value even though the number of semiconductor chips included in the semiconductor apparatus 200 is increased.
A signal outputted from the internal circuit INT of the first semiconductor chip 220 may be buffered by the second buffer 224, and the buffered signal may be outputted to the first buffer 223. The first buffer 223 may buffer the signal received from the second buffer 224, and output the buffered signal to the first substrate pad 212 and the package ball 211 through the first main pad 221. Signals outputted from the internal circuits INT of the second to fourth semiconductor chips 230, 240 and 250 may be buffered by the fourth buffer 234, the sixth buffer 244 and the eighth buffer 254, and the buffered signals may be transmitted to the second substrate pad 213 through the second auxiliary pad 232, the third auxiliary pad 242 and the fourth auxiliary pad 252, respectively. The signals transmitted to the second substrate pad 213 may be inputted to the first buffer 223 through the first auxiliary pad 222. The first buffer 223 may buffer the signals received through the first auxiliary pad 222, and the buffered signals may be outputted to the first substrate pad 212 and the package ball 211 through the first main pad 221. Accordingly, the signals outputted from the internal circuits INT of the first to fourth semiconductor chips 220, 230, 240 and 250 may be buffered by the first buffer 223, and may be outputted to the external device sequentially through the first main pad 221, the first substrate pad 212 and the package ball 211.
The switch 326 may selectively couple a first buffer 323 and a second buffer 324 based on the chip ID signal CID<0> of the first semiconductor chip 320 generated from the chip information generator 325. The switch 336 may selectively couple a third buffer 333 and a fourth buffer 334 based on the chip ID signal CID<1> of the second semiconductor chip 330 generated from the chip information generator 335. The switch 346 may selectively couple a fifth buffer 343 and a sixth buffer 344 based on the chip ID signal CID<2> of the third semiconductor chip 340 generated from the chip information generator 345. The switch 356 may selectively couple a seventh buffer 355 and an eighth buffer 354 based on the chip ID signal CID<3> of the fourth semiconductor chip 350 generated from the chip information generator 355. In a present embodiment, the switch 326 of the first semiconductor chip 320 which is coupled with a first substrate pad 312 may be turned on, and the switches 336, 346 and 356 of the second to fourth semiconductor chips 330, 340 and 350 which are not coupled directly with the first substrate pad 312 may be turned off. For example, the switches 326, 336, 346 and 356 may be turned on by only a chip ID signal associated with a semiconductor chip coupled directly with the first substrate pad 312. For example, all of the switches 326, 336, 346 and 356 may be turned on in response to only the code of 0,0. Therefore, the switch 326 of the first semiconductor chip 320 may be turned on, and the signal outputted from the first buffer 323 may be transmitted to the second to fourth semiconductor chips 330, 340 and 350 through a second substrate pad 313. All of the switches 336, 346 and 356 of the second to fourth semiconductor chips 330, 340 and 350 may be turned off, thereby blocking the third and fourth buffers 333 and 334 from each other, the fifth and sixth buffers 343 and 344 from each other and the seventh and eighth buffers 353 and 354 from each other. Therefore, an unnecessary loading which is likely to be added as the third buffer 333, the fifth buffer 343 and the seventh buffer 353 are coupled with the second substrate pad 313 may be decreased additionally.
The semiconductor apparatus 400 may further include a plurality of semiconductor chips which are sequentially stacked on the first semiconductor chip 420. The plurality of semiconductor chips may include substantially the same components as the first semiconductor chip 420. The first semiconductor chip 420 and the plurality of semiconductor chips may be classified into a predetermined number of groups. For example, the number of groups may be n (n is an integer equal to or greater than 2). In a present embodiment, the main pad of at least one semiconductor chip of each group is wire-bonded with the first substrate pad 412, the auxiliary pad of the at least one semiconductor chip of each group is wire-bonded with the second substrate pad 413, and the auxiliary pads of the semiconductor chips of each group may be wire-bonded with each other. The main pad of a remaining semiconductor chip of each group may not be wire-bonded with the first substrate pad 412. The auxiliary pad of the remaining semiconductor chip of each group may not be wire-bonded with the second substrate pad 413.

The buffer 423 of the first semiconductor chip 420 may buffer the signal received through the main pad 421 and provide the buffered signal to the auxiliary pad 422 such that the signal may be provided to not only the first semiconductor chip 420 but also the second semiconductor chip 430. A buffer 443 of the third semiconductor chip 440 may buffer the signal received through the main pad 441 and provide the buffered signal to the auxiliary pad 442 such that the signal may be provided to not only the third semiconductor chip 440 but also the fourth semiconductor chip 450. In a present embodiment, a loading which the external device expects for the semiconductor apparatus 400 may be a loading corresponding to 2 semiconductor chips (that is, the first semiconductor chip 420 and the third semiconductor chip 440). However, a loading which the buffer 423 and the auxiliary pad 422 of the first semiconductor chip 420 expect may be reduced to one half when compared to the cases of the semiconductor apparatuses 200 and 300 of
